- Description:
- The effects of different seedbeds on western larch germination and seedling mortality were assessed in a grand fir/ninebark habitat type in northern Idaho, USA. Two plots were established on each of four sites, and 150 western larch seeds (66% viable) were distributed on each of 16 randomly applied seedbed modification combinations (burned or mechanical scarified, mineral soil or duff, shaeded or non-shaded, caged or non-caged for protection from predation). Germination percentages and seedling development were significantly greater (4-10 times) on caged units than on uncaged units by mid-July. Shading did not sigificantly affect germination percentage or initial seedling establishment. No significant differences occurred in germination or initial seedling establishment between burned and unburned treatments. Mortality of seedlings, most likely caused by a month-long dry period with high temperatures, resulted in no significant differences in seedling numbers among treatments by mid-August the first year after seed dispersal. On the dry end of this species' range, there does not appear to be any difference in seedling survival from seedbed modification.
